植入式心律转复除颤器治疗室性心律失常的疗效分析

Evaluation of antiarrhythmic effect in the patients with implantable cardioverter defibrillator

植入式心律转复除颤器（implantable cardioverter defibrillator,ICD）的问世及发展改变了心源性猝死患者的命运,随着ICD技术改进及程控参数的多元化,其应用更为普及。ICD是治疗心血管疾病的利器,已成为心脏科医生防治恶性心律失常的重要手段。本文回顾了近5年来植入的42例ICD患者临床资料,旨在探讨ICD治疗室性心律失常的效果。1对象与方法 1.1对象自2008年7月以来。

Since 2008,42 patients were implanted ICD in our hospital.Of them,34patients were followed up（20male,62.5%）,including 9 single chamber ICD,1 double chamber ICD and 25CRT-D（one replaced）. There were 1 726 ventricular tachycardia（VT）episodes detected（510VT-treated and 1 216VT-monitored episodes）,moreover,99fast ventricular tachycardia（FVT）and 33ventricular fibrillator（VF）.The 589VT/FVT were treated by anti-tachycardia pacing（ATP）,among them,387（65.7%）were successfully stopped and 12episodes（2%）were got worse after ATP.The 18VT/FVT episodes were treated by low-energy converting and 8（44.4%）were stopped.Of VF episodes,3imappropriate detection were absorted after charging,15episodes were imappropriate discharged（3patients,8.8%）,1episode were stopped by ATP,17episodes were treated by high-energy defibrillate and 15（88.2%）were successfully stopped.
